Adding and Removing Users

Its also worth taking a look in /etc/passwd for listing of users.

adduser blah
userdel blah

groupadd users //Create a Group
adduser username users //Add a Member into the above group (Not making it their primary group)
//Putting a user into a group manually. This will not make it their primary group!
vi /etc/group
adm:x:4:user1,user2

Make the newgroup the PRIMARY one for the user:
Particularly useful, as adding a user into a group will not change their primary group!!

usermod -g newgroup user

Add a NEW user into an EXISTING Group

//This is what should be normally done, as it makes users their PRIMARY group, instead of making a new one!!
adduser --ingroup users username
//dont know if this is essential, but add them into the groups file in /etc -
adduser username users
